IMPROVEMENT lN TEMPORARY BINDERS FOR PAPERS.

Specification forming part of Lettcrs Patent No. 131,229, dated September 10, 1872.

To all whom it may concern:

Be it known that I, MoRRILL A. SHEPARD, of Lebanon, in the county of Saint Clair and State of Illinois, have invented a certain new and Improved Temporary Binder for Papers; and that the following is a full, clear, and eX- act description of the same,reference being had to the accompanying drawing forming part of this specification.

Figure l is a sectional view, showing the combination of the different parts. Fig. 2 is a view of the paper-file when locked up and ready for use.

In the drawing, Fig. 1, A A are two suitable bars of wood or metal for clamping the papers, in which are inserted two or more metal points, a a, to hold the papers in their place while .the clamps A A are unscrewed. The stem B has a square end for the purpose of receiving the screw-key, which is merely an ordinary spring clock-key. run on the other end of the stem B up to the collar S on said stem, for the purpose of drawing the two bars A A apart or shut, when required. The collar S also secures the stem B to the bar A. The plate D is secured to the A screw-thread is bar A' by screws, and has a screw-thread in it to receive the stem B. The plate F is also screwed or fastened to the oppositebar A. This plate is constructed so as to receive the stem B between the collars S s. This plate may be made with the notch, as shown, or it may becast onto the stem B between the collars.

The object of this arrangement is to obtain a neat, cheap, and durable paper-file, which can be securely locked by this screw-lock, the look at the same time being entirely out of the way, and answering the twofold purpose of a clamp-screw and lock.

What I claim as my invention is- 1. The screw-lock, consisting of the stem B, collars S '8, plates D F, arranged as described and set forth. a

2. The bars or clamps A A and points a a,

in connection with the screw-lock, the whole being arranged and operating substantially as herein described, and 'for the purpose set
